 * Use this BeanDefinitionParser when you need a "wrapper" element for an ObjectFactory. For example, suppose we have the

 * 
 * class Car { private ObjectFactory<Wheel> wheel; }
 * 
 * The following registration in the namespace:
 *
 * registerBeanDefinitionParser("wheel", new ObjectFactoryWrapper("wheel"));
 * 
 * would allow a config such as:
 * 
 * <car> <wheel> <prototype-object class="com.wheelsrus.BigWheel"> <properties> <spring:property name="tire" value="goodyear"/>
 * <spring:property name="diameter" value="35R"/> </properties> </prototype-object> </wheel> </car>
